Title: Data processing control system
Inventor: MATSUDA SHOHEI
IPC: G06F12/00
Filed: 1989-07-10
Abstract: PURPOSE:To completely maintain the synchronism of data by using the journal of the opposite system when system down occurs. CONSTITUTION:Both transactions 5, 6 communicating with each other are allowed to determine the definition or cancel of data updating of the system down side based upon the journal of the other system at the time of generating the system down by including conversation identifying information S003 in the journal 9a, 9b of both the systems by identification information setting means 21 which are allowed to correspond to each other by the information S003. Thus, an updating state determining means 24 checks whether the corresponding opposite transaction defines the updating based upon the opposite journal in each transaction whose updating state in the other system is not clear at the time of generating the system down and determines the data updating state of the down side. Consequently, an on-line system capable of maintaining complete synchronism can be obtained.
